Analysis of Grounding and Bonding Systems, 1st Edition
By Massimo Mitolo
Impact
Analysis of Grounding and Bonding Systems is intended for Electrical Professional Engineers (power) and students. The book supports the understanding of grounding and bonding systems with the necessary mathematical rigor, but also with detailed explanations and figures. The book analyses basic ground electrodes, which than allows the study of more complex grounding systems. The basic electrodes examined are: the sphere, the rod (i.e. cylindrical electrode), and the ground wire (i.e. horizontal cylindrical electrode). Further, Analysis of Grounding and Bonding Systems allows for the understanding of the behavior of complex grounding systems buried in uniform/non uniform soils under ground-fault conditions, thereby allowing the proper design of ground grids. In addition, the safety due to equipontential connections (i.e. bonding) between conductive metallic objects, such as equipment enclosures, is studied, proving that in some case bonding may increase the risk of electric shock.
Highlights
Readers will learn how to minimize hazardous interactions between grounding systems, cathodically protected pipelines, and heat networks. Also included is the analysis of the effectiveness of bonding systems against electric shock in the case of contact with electric vehicles during charge in the event of ground-faults, which is an upcoming issue challenging our safety.
Research
For the analysis of complex ground-electrodes configurations (e.g. ground-grids), the approach used is based on the Maxwell's method, or the superposition principle with the theory of the images, on the assumption that conductors forming the ground-electrodes are cylindrical elements that can be considered equipotential in the event of faults.
Development
Analysis of Grounding and Bonding Systems is based on thirty years of engineering practice in the field of power systems. The natural "fuel" of the book has been the everyday technical problems normally occurring during the electrical design, but also during construction.
